Product Components The HT Heating and Cooling System are comprised of the following major components:
Condensing Unit A 14 SEER heat pump condensing unit manufactured by Carrier and contains the environmentally friendly R410A Puron® refrigerant.
Recirculating Coolant Reservoir Holds 7.3 gallons of recirculating water for heating or cooling water circuit.
Make-up Coolant Float Valve Maintains the correct level in the recirculating coolant reservoir tank.
Recirculating Pump Recirculates cooling/heating water from coolant reservoir tank, through immersed bare tube evaporator coil, thru flexible lines, thru air handler and returning to coolant reservoir tank.
Energy Storage Tank The Energy Storage Tank located within the HT central unit, holds approximately 55 gallons of water that is utilized for two specific purposes: 1. The thermo-conductive property of water enables efficient heat transfer, and 2. The water stores excess energy to be used when the refrigeration system cycles off. The recirculating flow-through coolant lines are submerged within this R-10 insulated Energy Storage Tank and the recirculating coolant is efficiently chilled on the way to the equipment. Fill the Energy Storage Tank barrel with clean water upon installation and secure the lid. The water in the barrel stays in the barrel and you will only need to check the water level during periodic inspections.
HT Heating and Cooling System Functions The HT System performs 2 essential functions: • Refrigeration of water • Distribution of air generated by chilled or heated water 10 HT Heating and Cooling System User Manual & Installation Guide
• Recirculation of water
Refrigeration The HT Heating and Cooling System use coil technology to chill your equipment recirculating water. Immersed inside the 55 gallon energy storage tank are separate copper lines containing recirculating water and refrigerant. In the cooling mode, heat is removed from the recirculating water lines and the water contained within the energy storage tank. When the water within the energy storage tank reaches approximately 45 degrees, the refrigerant system cycles off. At this time, there are approximately 11,000 BTUs of energy stored within the 55 gallons of water in the energy storage tank. When the water in the energy storage tank reaches 52 degrees, the refrigeration cycles on again to continue cooling the recirculating water and the water in the energy storage tank. In the heating mode, heat is added to the recirculating water lines and the water contained within the energy storage tank. When the water within the energy storage tank reaches approximately 120 degrees, the refrigerant system cycles off. At this time, there are approximately 60,000 BTUs of energy stored within the 55 gallons of water in the energy storage tank. When the water in the energy storage tank drops to 114 degrees, the refrigeration cycles on again to continue heating the recirculating water and the water in the energy storage tank.
Thermostats Within the energy storage tank there are two thermostats, one maintaining the range of 45-52°F and one maintaining the range of 114-120°F. Within the recirculating reservoir there are also two thermostats, one maintaining the recirculating coolant temperature and a freeze-stat preventing the system from freezing should one of the cooling thermostats fail.
Recirculation The recirculating water pump draws suction from the water reservoir tank, through immersed bare tube evaporator coil, thru flexible lines, thru air handler hydronic coil and returning to water reservoir tank.
The recirculating water system consists of 5 parts: 1. Water reservoir tank located in the base of the HT central unit 2. Refrigerant and recirculating water lines submerged in water within the energy storage tank 3. Water recirculation pump 4. Air handler A low water level switch located in the recirculating water reservoir tank will interrupt power to the recirculation pump in the event of low recirculating water conditions.
Installation Instructions The HT Heating and Cooling System are typically delivered on a pallet. 1. Review the Location Checklist below before installing the HT System. 2.

15 HT Heating and Cooling System User Manual & Installation Guide Attaching Make-up, Supply and Return Lines
NOTE: The Make-up, Supply, and Return valves are all ½” NPT valves. NOTE: Use a backup wrench to secure coolant valves while installing connections to prevent damage to the lines. 1. Attach the Return line from your air handler to the bottom (Return) valves.
2. Attach the Supply line going to your equipment, to the middle (Supply) valves.
3. Attach the line from your Make-up water source (coolant tank or water hose) to the top (Make-up) valve.
Valves Shown in Closed Position TIP: To maintain the chilled water temperature and to prevent heat gain of the chilled Supply line, the HT central unit either needs to be close to the equipment or the Supply line needs to be properly insulated. This is especially important if the Supply line is exposed to high temperatures or hot surfaces. TIP: The chilled water leaving the HT central unit will be typically below the dew point so condensation may occur. Properly insulate the Supply line to prevent nearby surfaces from condensation damage.
Reminder about the Water in the Energy Storage Tank This HT Heating and Cooling System is a recirculating system with recirculating water flowing through a pipe that is submerged in the Energy Storage Tank. This recirculating water pipe is chilled/heated by refrigerant lines and the water within the Energy Storage Tank. The purpose of the water in the Energy Storage Tank is to store energy only. Do not remove water from the Energy Storage Tank during use.
Wiring Electrical Power to the HT Heating and Cooling System
DANGER ELECTRICAL SHOCK HAZARD – Disconnect Main Power!
16 HT Heating and Cooling System User Manual & Installation Guide
Before installing, modifying, or servicing the HT System, your main electrical disconnect switch must be in the OFF position. Your setup may have more than 1 (one) disconnect switch. Lock out and tag switch(es) with a suitable warning label(s).
All Electrical Work Must Be Completed By a Qualified Person Wire according to all national, state and city electrical codes. Failure to follow this warning could result in personal injury or death.
! CAUTION PREVENT REVERSE WIRING OF 3-PHASE As with all typical 3-phase systems, you can accidentally wire the HT System incorrectly to cause the compressor motor to run backwards. This is evident by excessive compressor noise, no heat being exhausted by the condenser fan within 1 minute, and recirculating water not cooling. Reverse any two leads to change the phase for proper rotation. Not correcting the wiring will cause the compressor to overheat, turn off, and stay off until the compressor protector has sufficiently cooled.
! CAUTION PREVENT BREAKAGE OF LINES - Fill Energy Storage Tank before Applying Power To prevent freezing and breakage of recirculating water lines, the Energy Storage Tank MUST be filled with water before power is applied to the HT System.
! CAUTION PREVENT SKIN DAMAGE – Do not Touch Refrigerant Lines in Storage Tank Refrigerant lines in the Energy Storage Tank can operate at temperatures below freezing. Touching these lines can freeze skin.

Liquid Line Dryer
Fig. 3 Refrigerant tubes and Energy Storage Tank heat exchanger should be evacuated using the recommended deep vacuum method of 500 microns. The alternate triple Evacuation method may be used (see triple evacuation procedure in service manual). Always break a vacuum with dry nitrogen.
CAUTION UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Never use the system compressor as a vacuum pump. Deep Vacuum Method The deep vacuum method requires a vacuum pump capable of pulling a vacuum of 500 microns and a vacuum gage capable of accurately measuring this vacuum depth. The deep vacuum method is the most positive way of assuring a system is free of air and liquid water. A tight dry system will hold a vacuum of 600 microns after approximately 7 minutes. See Fig. 4.
Make Electrical Connections Be sure field wiring complies with local and national fire, safety, and electrical codes, and voltage to system is within limits shown on unit rating plate. Contact local power company for correction of improper voltage. See unit rating plate for recommended circuit protection device. NOTE: Operation of unit on improper line voltage constitutes abuse and could affect unit reliability. See unit rating plate. Do not install unit in system where voltage may fluctuate above or below permissible limits. NOTE: Use copper wire only between disconnects switch and unit.

START-UP
CAUTION
30 HT Heating and Cooling System User Manual & Installation Guide
UNIT OPERATION AND SAFETY HAZARD Failure to follow this caution may result in personal injury, equipment damage or improper operation. • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure. • Compressor dome temperatures may be hot.
CAUTION PERSONAL INJURY HAZARD Failure to follow this caution may result in personal injury. Wear safety glasses, protective clothing, and gloves when handling refrigerant and observe the following: Front seating service valves are equipped with Schrader valves.
Follow these steps to properly start up system: 1. After system is evacuated, fully open liquid and vapor service valves. 2. Replace stem caps after system is opened to refrigerant flow. Replace caps finger-tight and tighten with wrench an additional 1/12 turn. . 3. If the Energy Storage Tank was emptied, confirm that it was refilled. 4. If Water In / Water Out lines were cut, confirm that they were reconnected and purged of air. 5. Confirm that Water In / Water Out lines are open and flowing. 6. Close electrical disconnects to energize system 7. Turn on the HT System by pushing the ON/OFF switch located on the front of the Energy Storage Tank Cabinet. Light in the switch will illuminate. a.Note: If the unit is noisy and/or cooling is not being achieved, the compressor is probably running in reverse direction. Remedy is to change any 2 Incoming power leads. 8. Operate unit for 30 minutes.
Check Charge Desired sub cooling is 12-13 °F and is shown on unit rating plate. Charging method is shown on information plate inside condensing unit. To properly check or adjust charge, conditions must be favorable for sub cooling charging. Favorable conditions exist when the outdoor temperature is between 70°F and100°F (21.11°C and 37.78°C), and the Energy Storage Tank water is between 70°F and 90°F (7.22°C and 26.67°C). Follow the procedure below: Unit is factory charged for 15ft of line set. Adjust charge by adding or removing 0.6 oz. /ft. of 3/8 liquid line above or below 8ft (2.44 m) respectively. For standard refrigerant line lengths (50 ft./24.38 m or less), allow system to operate in cooling mode at least 30 minutes. If conditions are favorable, check system charge by sub cooling method. If any adjustment is necessary, adjust charge slowly and allow system to operate for 30 minutes to stabilize before declaring a properly charged system. If the Energy Storage Tank water temperature is above 80°F (26.67°C), and the outdoor temperature is in the favorable range, adjust system charge by weight based on line length and allow the Energy Storage Tank water temperature to drop to 80°F (26.67°C) before attempting to check system charge by sub cooling method as described above. NOTE: If line length is beyond 50 ft. (24.38 m) or greater than 30 ft. (6.10 m) vertical separation, See Long Line Guideline for special charging requirements. Final Checks IMPORTANT: Before leaving job, be sure to do the following: 1. Ensure that all wiring is routed away from tubing and sheet metal edges to prevent rub-through or wire pinching.
31 HT Heating and Cooling System User Manual & Installation Guide
2. Ensure that all wiring and tubing is secure in unit before adding panels and covers. Securely fasten all panels and covers. 3. Tighten service valve stem caps to 1/12-turn past finger tight. 4. Leave this User Manual & Installation Guide including Wiring Diagram with owner.
CARE AND MAINTENANCE For continuing high performance and to minimize possible equipment failure, periodic maintenance must be performed on this equipment. Frequency of maintenance may vary depending upon geographic areas, such as coastal applications. See Owner’s Manual
REFRIGERANT CHARGE ADJUSTMENTS Liquid Line
0.5 oz. /ft. 3/8 (Factory charge for line set = 3 oz. / 85.05 g)
Charging Formula: [(Lineset oz. /ft. x total length) – (factory charge for line set)] = charge adjustment Example: System has 20 ft of line set. Formula: (.50 oz. /ft. x 20ft) – (3 oz.) = 7 oz. Net result is to add 7 oz. of refrigerant to the system.
LONG LINE APPLICATIONS An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units. For Air Conditioner systems, the chart below shows when an application is considered Long Line. AC WITH 410A REFRIGERANT LONG LINE DESCRIPTION ft.
